three eggplants, one cut in half

Keeping blood pressure under control is crucial in maintaining good heart health and reducing the likelihood of a stroke. There are a number of non-drug approaches that have research backing, such as following a DASH diet rich in vegetables and fruits. We haven’t seen any studies of eggplant water, but many readers are interested in this approach.

How Do You Make Eggplant Water?

Q. I have been drinking “eggplant water” I made from floating half a dozen thinly sliced pieces of raw eggplant on top of two or three quarts of water in a bowl. I discard the eggplant after a few hours, when it starts to turn brown. I have been drinking 60 ounces of this water daily for about two weeks.

My weight dropped 7 pounds and my blood pressure is down from 150/80 to 124/66. This might be helping my insulin resistance, which made it hard for me to lose weight before.

A. When cells don’t respond efficiently to insulin, blood sugar control is more difficult. Losing weight is also more challenging, but people who shed pounds often lower their blood pressure.

You are not the first reader to mention eggplant water for hypertension, but the previous recipe called for just one ounce daily, not 60. We don’t know for sure why this might be helpful, but we have a couple of hypotheses.

Anthocyanins and Blood Pressure:

Eggplants are rich in dark purple compounds called anthocyanins (Plant Science, Aug., 2016). Research on anthocyanins has not shown that they lower blood pressure consistently (Medicine, April, 2016).

However, some extracts of eggplant appear to inhibit angiotensin-converting enzyme (ACE), just as certain blood pressure medicines do (Bioresource Technology, May, 2008). It is possible that alpha-glucosidase inhibiting enzymes in eggplant also help with insulin resistance. Alpha-glucosidase inhibitors from other plants are being investigated for their ability to keep blood sugar from soaring after meals (Mini Reviews in Medicinal Chemistry, April, 2010).

You will find a number of other non-drug approaches for controlling hypertension along with a discussion of the pros and cons of common medications in our guide to Blood Pressure Treatment. If you are interested in more details on following a DASH diet (Dietary Approaches to Stop Hypertension), you’ll find them in our book, The People’s Pharmacy Quick & Handy Home Remedies.

    I have been told to NEVER eat raw eggplant! They say that it is poison when raw. I do plan to try the eggplant water on my husband though, because a close friend of mine said the first time trying it, it dropped her BP quite a bit. Hopefully, it will help his blood sugar levels as well.

    Please help me understand why / how eggplant water is more effective than eating raw eggplant.

    What does eggplant water taste like? Can you drink it without adding anything else to it?

    I have a high EOS count of 6. What does this mean?

    My husband read this a while back and has been pushing me hard to try it. After reading the full article and comments, I’m going for it tomorrow. Wish me luck. I’ll report back here in a month, unless I see outstanding results sooner. Thanks for all the previous posts.

    I have been on eggplant water for 4 months now, and now I don’t take any off my three pills for high blood pressure since I went to my doctor and checking my blood count and blood pressure. My cholesterol got lower too. Thanks God for the eggplant.

    This is an ancient remedy used in my country of origin (Cuba) and I’ve known about it since childhood as I would hear the adults talk about it. I have a friend who lowered her BP by drinking eggplant water.
    I had totally forgotten about this natural way to help lower high BP, cholesterol, triglycerides as well as excess body weight and fat. I’ve seen it with my own eyes. I have had it before with much success for cleansing my system and losing weight/fat.
    I’m glad I remembered it because I will start drinking this water everyday. The way my people have always drank it is “drink it as you would regular water throughout the day”. In other words, you can drink most or all of your daily water intake in the form of eggplant water. It’s also a natural diuretic. You’ll see how well you will feel.
    All I know is…I’m in!
    I wish all of you a very healthy and happy life!

    I tried this but it didn’t lower my blood pressure. I drank at least a cup a day for three weeks and there wasn’t any change at all in my pressure. I did however feel like my breathing was more open and clear. Not that it was bad before but there was a difference. Since I hate drinking plain water I will keep drinking eggplant water. Now that I know it doesn’t lower my blood pressure at all I will consume more of it throughout the day. Hey maybe the weight loss claim will work but I didn’t see any difference there either so far.

    I have what is called “essential” high blood pressure, which some Drs. don’t believe truly exists. It’s when your pressure goes up and down, seemingly for not much reason. Before I did a web search regarding eggplant, I accidentally ran into its benefits. I had a medium sized eggplant on my counter, decided one night to consume it. Sliced it up, floured it, browned it in olive oil, made a gravy out of the browned flour left over in the pan, into which I put some onion, dill, arugula, basil, bay leaf, parsley, rosemary — chosen simply because that’s what I have growing in my pots on my porch!
    Consumed the entire eggplant, and some gravy. Happened to take my BP again, and found it had dropped quite a bit. It was up around 200 over 100 before I ate. So I monitored it quite closely. When it got down to 80 over 50 (not foolin’ at all!!!), I was beginning to wonder if I should go to the hospital, but I felt fine. It leveled off. Then I did my internet search and was stunned to find out about eggplant being able to lower BP!
    So now, in between my meds, if my pressure goes up, I do the eggplant thing a little bit. Works every time! Sometimes it keeps it down quite a long time, and I have to delay taking my medicine, but that type of stuff is risky, and you have to be careful, especially if you have “essential” high BP as I have. I am not sure, in my case, if the herbs are essential, so I am being very careful with trying the process of elimination.
    It seems onions play a big part in it all. Also, by VERY CAREFUL MONITORING with a wrist pressure cuff, I have learned a lot of things. Some of the things that make my pressure go up and down, which all seem very logical, is 1) forgetting to take my pill on time, 2) staying up too long, beyond what my body wants me to (I am almost 80 years old), 3) sometimes sugar – sweets of any kind (most sweets have a lot of salt in, believe it or not), 4) sometimes chocolate, 5) stress (of course!), 6) not getting at least 8 hours of sleep, 7) not resting often enough (work full time at Wal Mart in the garden center, VERY active), 8) doing ANY project at break neck speed!, 9) weighing too much (I am 4 ft 11 inches, have weighed 165, now weigh 130, have some to go yet, but the more I lose, the better my BP behaves!, 10) salt! salt, salt, salt! You need some, but mostly it can be a real killer!
    So listen up, all you high blood pressure sufferers out there! By the way, just in case you don’t understand how high BP can give you the tendency to a stroke, let me explain: Have you ever had one of those long skinny balloons, or any balloon, that you blew up and down and up and down, until it got weak in one spot and a “bubble” would pop out on the side? … and eventually the “bubble” would burst? Same thing with your blood pressure, up and down, or too high constantly makes your blood vessels weak, until BINGO! .. comes the burst and thus a stroke.
    A lot of my friends also do not know what the two numbers in the blood pressure represent. The top one is for the pressure exerted on your veins when your heart beats, and the lower one is the pressure left on your veins when your heart is at rest between beats. Does all this scare you death? It will kill you to death, if you don’t pay attention to what you eat, how you behave, and what your doc says! You all have a great day, better yet, MAKE it a great day! God bless you all richly.

    why can’t you produce the same results by just eating cooked eggplant? will cooked eggplant help to reduce hypertension?

    I tried the eggplant water remedy to lower my blood pressure. After drinking 3 or 4 glasses a day for a week, my blood pressure dropped from 150/90 to 124/80 but my husband is concerned about the solanine in eggplant. Do you think this dosage is a risk for solanine poisoning?
